Trying to take the best of both worlds of LSD and Interval-oriented/Coe-ish training, would this work? To do all of your running super EZ, but have just a mile worth of quality everyday to keep speed up?
EZ running everyday, PLUS:
Su: 16*100m @ 800m pace
M: 1*Mile @ 10k Pace
T: 4*400m @ 5k Pace
W: 8*200m @ Mile Pace
Th: 4*400m @ 5k pace
F: 16*100m @ 800m pace
Sa: 8*200m @ Mile Pace
